This guide will walk you through everything you need to know about getting an EIN for your freelancing business in Colorado in 2026.

What is an EIN?

An Employer Identification Number (EIN) is a unique nine-digit number assigned by the IRS to business entities operating in the United States. It's essentially a Social Security number for your business. While often associated with employers, an EIN can also be used by sole proprietors, LLCs, and other business structures for various purposes.

How to Apply for an EIN

  1. Determine Your Eligibility: Ensure your freelance business is eligible for an EIN. Generally, if you've formed an LLC or need to hire employees, you're eligible. Even as a sole proprietor, you might want an EIN for financial privacy.
  2. Choose Your Business Structure: Decide on your business structure (sole proprietorship, LLC, etc.). If forming an LLC, complete the formation process with the Colorado Secretary of State. Online filing is typically the fastest method.
  3. Gather Required Information: Collect all necessary information, including your Social Security number (or ITIN), business name, business address, and the reason for applying for the EIN.
